Thirteen Russians and three Russian entities were charged Friday with an elaborate plot to interfere in the 2016 U.S. presidential election, federal prosecutors announced Friday.

The indictment , brought by the office of special counsel Robert Mueller, alleges that Russians used bogus social media postings and advertisements fraudulently purchased in the name of Americans to sway political opinion during the race between Republican Donald Trump and Hillary Clinton, his Democratic opponent.

The charges are the most direct allegation to date of illegal Russian meddling in the election.

The goal, the indictment says, was to “sow discord in the U.S. political system, including the 2016 presidential election.”
